dmesg|grep-i"XID"[357.496185]NVRM: Xid(PCI:0000:b1:00):79, GPU has fallen off the bus.[357.497065]NVRM: Xid(PCI:0000:4b:00):154, GPU recovery action changed from 0x0(None)to 0x2(Node Reboot Required)[357.497078]NVRM: Xid(PCI:0000:b1:00):154, GPU recovery action changed from 0x0(None)to 0x2(Node Reboot Required)Xid Errors表
常见错误
| XID代码 | 含义 | 严重性 | 典型原因 |
|---|---|---|---|
| 32 | 推送缓冲区流无效或损坏 | 中 | 驱动Bug、显存溢出 |
| 43 | GPU执行超时 | 高 | 计算任务死锁、散热不良 |
| 74 | NVLink链路异常 | 致命 | 硬件损坏、固件故障 |
| 79 | GPU从总线脱落 | 致命 | 电源故障、PCIe插槽接触不良 |
| 48 | 显存页分配失败 | 中 | 显存不足、驱动兼容性问题 |
常见维修方法
对于Xid (PCI:0000:b1:00): 79, GPU has fallen off the bus.：将两张显卡交换位置，启动后使用服务器显卡，若产生掉卡，使用dmesg | grep -i "XID"查看信息，如果后续运行中依然报错Xid (PCI:0000:b1:00): 79, GPU has fallen off the bus.说明是PCIe插槽或电源线有问题，如果报错变成Xid (PCI:0000:4b:00): 79, GPU has fallen off the bus.说明显卡有问题。
